4 Claims.

The invention relates to powder cases or boxes for retaining a powder or similar material in loose form together with a puff or similar element designed to apply the powder material.

It has for an object, in a box of this character, the provision of means whereby the retained powder, as the supply thereof becomes depleted, remains readily accessible for application to the puff without requiring shaking or other manipulation of the container as a whole, and without scattering or waste of the powder.

A further object of the invention resides in the provision of a box of the aforesaid nature which may be maintained in sanitary condition and the powder sealed when the box is not in use.

A still further objector" the invention resides in the provision of a loader or refill member particularly suitable for use with more or less elaborate and expensive containers which it is not desired to discard when the initial charge of powder is exhausted. Another object of the invention is to afford a loader element of this type of an elastic or resilient material which, while securing the powder against scattering, will yield under pressure applied thereto by the puff element for discharging powder thereon, and be collapsible more or less under its own weight to conform to the receding powder level therein, said powder normally serving to distend the said loader element.

A still further object of the invention resides in the provision of means for sealing the loader element against the entrance of moisture when the same is not in use, or for preventing spilling of the powder when it is desired to transport the loader element.

In the accompanying drawing, which illustrates a preferred embodiment of the invention, Fig. 1 illustrates the novel powder box in plan view, with the cover removed.

Fig. 2 is a vertical section therethrough.

Fig. 3 is a horizontal section through the box taken on the line 33, Fig. 2 of the drawing.

Fig. 4 is a vertical section through the powder box, with cover removed, and illustrates the loader element in partly collapsed condition.

Referring to the drawing, it designates a casing of suitable shape and size and designed to afford a compartment within which is to be mounted a loader element i i to substantially occupy the lower portion of the container or box it said element resting upon the bottom thereof as shown in Figs. 2 and 4.

This loader element consists of an elastic or resilient material, such as rubber, which may readily be shaped, as by dipping a form of the desired contour into liquid rubber, to conform to the interior of the box i d as Well as to provide the series of circumferential corrugations l2 forming of v the said element a bellows or like collapsible 5 member. The powder 53 for use is filled into the said loader element i through an opening I t provided in its top, which opening may be arranged to be closed by a removable disk i5 having perforations 26 designed, for controlling the outflow of the powder, to register with the perforations ii of a rotatable slide it pivoted to the disk l5 as at its center is. The powder i3 within the loader it serves to distend the same and may be readily sealed therein by turning the slide l3, through a tab 2% attached thereto, to a position to avoid registry of the respective sets of perforations it and it, as when the box is not in use or when it is desired to transport the loaded box or to store the loader element as refills.

The cooperating disks l5 and it may be of any suitable material, such as celluloid, hard rubher or metal; and the former disk is arranged to be frictionally held at its circumference within the annular recess 2i formed by doubling over the inner edge of the top of the loader element, it being desirable to this end to also roughen, as by knurling, the circumference of said disk. This doubled-over edge will be stretched over the circumference of the said disk l5 to hold the same securely under the natural resiliency 01 the loader element material, which resiliency will tend also to direct the powder toward the outlet opening it in the top of the element as well as conforming the shape of the element more or less to the quantity of powder retained therein. When the two sets of perforations are in registry, the powder may be received upon a puff 5 22 or like member by pressing the same downwardly upon the top of the loader element.

If it be desired to refill a loader element, the sealing disks i i and it may readily be separated from the body of the element by stretching the edge or recess 2i; and, similarly, the said disks may conveniently be replaced when the powder has been loaded into the said element.

By combining an outer container with a loader element of the nature set forth, refilling of the same is readily provided for, and not only is the powder readily and conveniently accessible at all times but it is sanitarily maintained and mat be dispensed with a minimum of waste and without undue scattering. As the supply becomes depleted, the element it will tend to collapse, as indicated in Fig. 4, to conform to the diminished contents which will be thus always accessible to the puff pressed over the outlet i l.

I claim:

1. A loader element for powder boxes adapted to rest upon the bottom thereof and free at the opposite end, said element, comprising a seamless, one-piece elastic rubber receptacle of a thickness sufficient to afford a self-sustaining powder receptacle and having a succession of vertically disposed circumferential folds whereby the element may be collapsed, to follow the contents as the same are depleted, by exerting pressure upon the top thereof which is provided with a centrally disposed outlet opening, and means to seal said opening.

2. A loader element for powder boxes adapted to rest upon the bottom thereof and free at the opposite end, said element comprising a seamless,

one-piece elastic rubber receptacle of a thickness.

SllfilClEIlt to afford a self-sustaining powder receptacle and having a succession of vertically disposed circumferential folds whereby the element may be collapsed, to follow the contents as the same are depleted, by exerting pressure upon the top thereof which is provided with a centrally disposed outlet opening, and the said receptacle having a top inturned flange extending beyond the inner edges of the folds to afiord a centrally disposed outlet opening, and means to seal said opening.

3. A loader element for powder boxes adapted to rest upon the bottom thereof and free at the opposite end, said element comprising a seamless, one-piece elastic rubber receptacle of a thickness sumcient to afford a self-sustaining powder receptacle and having a succession of vertically disposed circumferential folds whereby the element may be collapsed, to follow the contents as the same are depleted, by exerting pressure upon the top thereof which is provided with a centrally disposed outlet opening, and the said receptacle having a top inturned flange extending beyond the inner edges of the folds to afford a centrally disposed outlet opening, the

material about the edge of opening being doubled upon itself to afford an annular recess, and a perforated disk fitting within said recess and removably retained therein under the inherent resiliency of the rubber.

4. A loader element for powder boxes adapted to rest upon the bottom thereof and free at the opposite end, said element comprising a seamless, one piece elastic rubber receptacle of a thickness sufficient to afford a self-sustaining powder receptacle and having a succession of vertically disposed circumferential folds whereby the element may be collapsed, to follow the contents as the same are depleted, by exerting pressure upon the top thereof which is provided with a centrally disposed outlet opening, and the said receptacle having a top inturned flange extending beyond the inner edges of the folds to afford a centrally disposed outlet opening, the material about the edge of the opening being doubled upon itself to afiord an annular recess, a perforated disk fitting within said recess and removably retained therein under the inherent resiliency of the rubber, and a slide member rotatably mounted upon the disk having perforations adapted for registry with the perforations of the said perforated retained disk.
